Guy - I'm getting annoyed by all this shouting and stamping - its got nothing to
do with what is ACTUALLY being discussed!
I work with customers who have trouble even getting a wireless connection at
time and many of our systems have to cater for periods without access to the
internet. The BULK of my systems are accessed by (web)browsers on many different
devices most of which are never actually logged into our sites so currently we
have no way of even identifying their timezone. Stephen has already explained
the limitations on matching timezones with countries and I'm not really bothered
where that matching is done as long as there is something consistent and correct
I can use. If that has to be outside TZ then fine.
But this is just a very small part of the use of the tz data, and my main
interest is historical times, where we have the location. OSM has a growing
archive of that. All I need to be able to identify is which timezone a location
is in on a particular date. THIS is where the shape files defining ISO3166 codes
can be useful and again I'm looking to match that data to the timezone data. At
some point we will also map the tz zones and their historic changes, but the
current database is countries.
Now if you have something constructive ... please don't pad it out with
unnecessary information ...
